I made a mistake that I can't undo but I will be okay, just a heads up.

I cut the end off the sub frame connector like required while the floor pans were out. What I did was cut the whole end off and the rail widened (sprung open a little at the top). After checking in again, he left part of the top of the end.

So, I think the support is there ans what little loss is structural support I lost I gained it back with the connectors. But I had marked ans welded the pans

So, a lesson learned.
